Langflow: Logout button does not clear session ### Summary The logout button does not clear the session. The previous user stays logged in unless another user explicitly logs in. ### Details Not in auto login mode. Hosted on localhost. `access_token_lf` remains present in both Local Storage and Cookies. `refresh_token_lf` remains present in Cookies. **Root cause:** the `/logout` endpoint deleted the authentication cookies without matching the original `httponly`/`samesite`/`secure`/`domain` parameters, so the browser kept them; additionally the frontend did not clear the auth cookies on logout. ``` LANGFLOW_AUTO_LOGIN: "False" LANGFLOW_SUPERUSER: <set> LANGFLOW_SUPERUSER_PASSWORD: <set> LANGFLOW_SECRET_KEY: <set> LANGFLOW_NEW_USER_IS_ACTIVE: "False" LANGFLOW_ENABLE_SUPERUSER_CLI: "False" ``` ### PoC Click Logout. Hit refresh to return to previous screen. ### Impact Users on shared computers may falsely believe they have terminated their session. ### Patches Fixed in **1.7.0** (PRs #10527 and #10528). The logout endpoint now deletes the auth cookies using the same parameters they were created with, and the frontend clears the auth cookies on logout. Upgrade to **1.7.0 or later**.
